Need for compressed air<\/h3>\n<\/div><\/div>

Compressed air is the air that is compressed for use as power.<\/span>
\nIt is essential for plant operations in all industries around the world,
\nincluding vessels, electricity, electronics, semiconductors, petrochemicals, plants, machinery, engineering, food, and more.
\nCompressed air is also a source of energy for operating various machinery and equipment in industrial sites.<\/p>\n<\/div><\/div>

<\/div>

What happens if compressed air is used without being managed?<\/b><\/span><\/p>\n<\/div><\/div>

<\/i><\/div>

It can cause product defects, stops in production lines, and deterioration of quality.<\/b><\/span><\/p>\n<\/div><\/div><\/div>

              01 Moisture<\/span><\/strong><\/p>\n<\/div><\/div>

              When air is compressed, the concentration of relative humidity increases as the volume decreases, resulting in a large amount of moisture.
              \nMoisture is a major contaminant of compressed air systems and creates condensation where bacteria live.
              \nAccordingly, there is a high risk of corrosion inside the pipe, which makes it very important to properly maintain the dew point.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

              \"\"<\/div><\/div><\/div><\/div><\/div>

              02 Oil<\/span><\/strong><\/p>\n<\/div><\/div>

              If the air compressor uses lubricating oil, it is inevitable that oil is mixed in with the compressed air. Oil exists in a variety of forms.
              \nThe amount of oil contained in compressed air is quite difficult to guess, so it is best to check it directly.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

              \"\"<\/div><\/div><\/div><\/div><\/div>

              03 Foreign Matter<\/span><\/strong><\/p>\n<\/div><\/div>

              There are about 140 million solid particles per 1\u33a5 of air in the atmosphere. Of these, 80% are less than 2\u339b in size.
              \nIf such air flows into the air compressor, the operating parts of the compressor may be damaged by the solid particles.
              \nTherefore, a filter with a suitable filtration capacity and efficiency should be used.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>

              <\/div><\/div><\/div><\/div><\/div><\/div><\/section>

              It is difficult to identify moisture, oil, and foreign substances contained in the air with the naked eye
              \nbecause the particles are very small.<\/strong><\/p>\n

              JEONGWOO Flow directly measures the condition of compressed air used in the field
              \nand diagnoses whether it complies with ISO standards for compressed air quality for each industry.
              \n<\/b><\/span><\/p>\n

              Below shows the quality standard for compressed air for representative industries, which was published by the ISO
              \n<\/strong>(International Standardization Organization.)
